RF Power Tool Purpose
•
The RF Power Tool is designed for non-RF engineers, to evaluate
Solid-State RF and prototype innovative solutions
•
This modular bench-in-a-box removes the need to invest in a full RF bench
while making access to RF easy as a result its intuitive user interface
•
Combines an RF generator and test bench capabilities

PA Module box
• Power Amplifier lineup with
couplers and sensors
• Orange case
• Documentation:
•
Circuit Information document
•
Measured data (Pin/Pout, Frequency sweep)
User Supplied Equipment
•
High power supply
−
Size is 2x rated power of Power Amplifier at rated voltage
of the final transistor
− Suggest using TDK Lambda or MeanWell server brick style
•
Load
−
•
Suggest using Bird or Dielectric labs that are rated for
frequency and power of the PA
Cooling method
−
Easiest is large heatsink with 6-inch square flat surface to
mount the PA.
− 6 x 12, 3-inch high will suffice for 100 W without fan,
250 W with fan
•
Connecting cable between PA and load
−
Be careful to select a cable suitable for the power of the
amplifier and have minimum loss
− Bigger is better
